Hebrews 11:6 ...without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him.
Abraham was definitely not perfect but he certainly is a good example to us of choosing to believe in the promises of God. Abraham heard God speak to him to leave his family, his home and his country and go to a place that God said would be given to him and his descendants. So, Abraham, acted on the command believing that God would be true to his word. The truth is that Abraham and Sarah did not even have kids, so they are leaving everything behind to go to a strange and foreign land so that they and their descendants could inherit this land that God had promised? What descendants? But Abraham believed that God was as good as His Word, so he responded as though what God had said was as good as done.
Along the way he had moments of doubt, but those moments were never enough for him to turn his back on the promises of God. Abraham surrendered his present situation because he remained confident that God's Word was true. That was pleasing to God.
What are the promises God has given you about your future? Are you living as though they are real even if we haven't seen signs of it yet?
God promises that one day His Son will come again to take us to heaven - are you living by faith of that promise?
God promises that this world is not our home, we are pilgrims in this land. Our home is heaven and we must live today with heaven in mind. Do our actions and choices point to our belief that we are just passing through or do we live as though this life is all we have?
